Prevalence of incidental clinically relevant pancreatic cysts at diagnosis based on current guidelines.

Background: Most pancreatic cysts (PCs) found incidentally by CT and MRI scans might not be clinically important according to the Fukuoka guidelines, the American Gastroenterological Association (AGA) guidelines and European guidelines.

Aims: To determine and compare the prevalence of incidental clinically important PCs (CIPCs).

Methods: Abdominal contrast-enhanced CT or MRI scans performed during a one-year period were retrospectively reviewed to identify incidental PCs.

Finding sessile serrated adenomas: is it possible to identify them during conventional colonoscopy?

Background And Aim: Proximal colorectal cancer may arise from sessile serrated adenomas (SSAs). Recognition of these lesions during colonoscopy can optimize the endoscopic approach. We aimed to identify specific endoscopic features of SSA with conventional colonoscopy.

[Colorectal cancer screening with colonoscopy].

Colorectal cancer is one of the leading causes of cancer death worldwide and also in Argentina. In the past few years colorectal cancer screening has become more popular and colonoscopy has been postulated as the gold standard. In this review we analyzed the evidence supporting this method in contrast with its complications and disadvantages.

[Prevalence of serrated adenomas of the colon and association with synchronic and metachronic neoplastic lesions].

Objective: To determine the prevalence of serrated adenomas (SA), the frequency of high grade dysplasia (HGD) and adenocarcinoma in these polyps, and the association with synchronic (SNL) and metachronic neoplastic lesions (MNL).

Methods: Reports from patients undergoing colonoscopy and polypectomy from January 2003 to April 2010, were obtained from our electronic database. SA were reanalyzed by two pathologists and classified on the basis of Snover's diagnostic criteria.

[Celiac disease and risk of colorectal neoplasia].

Background: Although small bowel and esophagus neoplasia are recognized to occur more frequently in patients with celiac disease, the association with colorectal cancer is still controversial.

Objective: To determine the risk of colorectal neoplasia among patients with celiac disease.

Methods: A case-control study was conducted using the gastroenterology and endoscopy unit electronic data base.

[Diffuse gastric cancer associated with Ménétrier's disease].

Background: Ménétrier's disease is a rare disease of the stomach generally described as hypertrophic gastropathy. Its etiology is unknown and its malignant potential is controversial. Only a few reports supporting its association with gastric cancer have been found.

[Role of antibodies in celiac disease after one year of treatment to predict the adherence to gluten-free diet].

Introduction: The celiac disease (CD) is characterized by a permanent sensitivity to gluten. The treatment for this disease is the life-long strict compliance with a gluten-free diet (GFD). The average of compliance with GFD ranges between 15% and 80%.

[Surveillance colonoscopy before scheduled: is it worthwhile?].

Objective: To determine de incidence of colonic polyps in colonoscopies performed before scheduled and to identifY the clinical and endoscopic features that predicted this finding.

Methods: All patients who underwent at least two complete colonoscopies less than three years apart were retrospectively identified in our computerized database. We excluded patients with high risk of colonic neoplasm requiring a new colonoscopy in less than three years.

A colorectal mosaic pattern might be an endoscopic feature of collagenous colitis.

Background And Aims: The endoscopic aspect of the colorectal mucosa in those patients with collagenous colitis is usually normal, or with non-specific changes. Until now it had never been related to a mucosal pattern of mosaic type. Our aim was to determine the diagnostic accuracy of the presence of mosaic pattern in the colorectal mucosa for collagenous colitis.

Lymphoepithelial cysts of the pancreas: case report and review of the literature.

The aim of this report was to describe the clinical and pathologic features of lymphoepithelial cysts of the pancreas, establish the differential diagnosis of other pancreatic cysts, and review the literature. A 53-year-old man was incidentally diagnosed with a pancreatic lesion after an abdominal CT scan. This study showed a solid mass in the tail of the pancreas not enhanced by helical CT.
